Study Notes
Echidnas and Climate Change
- Echidnas, also known as spiny anteaters, are small, egg-laying mammals that live in eucalypt forests in Australia and play a crucial role in combating climate change.
- They dig holes in search of food, creating pits and mounds of soil that help to capture and store carbon dioxide (CO2) from the atmosphere.
How Echidnas Help Combat Climate Change
- Fallen leaves, seeds, and other organic matter collect in the pits left behind by echidnas, bringing them into contact with soil microbes.
- Soil microbes break down the organic matter, incorporating carbon into the soil and helping to build up soil carbon.
- Without the pits, sunlight would break down the organic matter, releasing CO2 into the air.
Ecosystem Science and Carbon Storage
- Supporting healthy ecosystems helps to boost the growth of organisms that absorb CO2 from the atmosphere, such as algae, plants, and some bacteria.
- These organisms use CO2 from the air and water to make food for themselves through photosynthesis, and the carbon in that gas becomes part of their bodies.
Animal-Driven Nature-Based Solutions to Climate Change
- Some animals help plants and algae thrive by protecting them from grazers, while others help plants reproduce or act as "gardeners" to tend to their ecosystems.
- Animals can even alter the non-living parts of their ecosystem, such as soil and air.
- Protecting animal "climate heroes" like echidnas is crucial for combating climate change.
Echidna Behavior and Impact
- An individual echidna can move up to eight tons of soil per year, creating many holes that help to trap carbon in the soil.
- Pits near patches of trees and shrubs capture more carbon than those in areas without much greenery, highlighting the importance of forest ecosystems.
